Scientific classification

Class: Aves

Order: Passeriformes

Family: Fringillidae

Forms three well-defined subfamilies#R, including Euphoniinae, previously placed in Thraupidae. Also includes Drepanidini, sometimes treated as a separate family (as in HBW), but here considered merely a tribe of Carduelinae. Extensive phylogenetic data available, and comparatively few species remain wholly unscreened; nonetheless, study of internal relationships has been confounded by recurring plumage patterns and use of similar feeding niches by taxa that prove to be far from closely related.

Subfamily: Carduelinae

Tribe: Carpodacini

Previously considered to include species now in Agraphospiza, Procarduelis and Haemorhous (see all three, below); now in different tribes. As traditionally constituted, was extensively polyphyletic, and in response now restricted to Old World species. In order to resolve paraphyly, present genus expanded to incorporate: two monospecific genera considered basal within this lineage, Chaunoproctus (†Carpodacus ferreorostris) and Haematospiza#R; three other monospecific genera, Kozlowia, Uragus and Pyrrhospiza#R#R; one species from Leucosticte#R; and one hitherto placed in Pinicola or Propyrrhula (as in HBW)#R#R. Some authors have isolated C. erythrinus in Erythrina#R.
